VETERINARY DENTAL FLOAT.

SPECIFICATION forming part of Letters Patent No. 792,666, dated June 20,1905.

Application filed November 15, 1904. Serial No. 232,908. i

To all whom it may concern.-

Be it known that we, GARNET J. REED and ALBERT MEIERI-IOFER, citizens ofthe United States, residing at Minonk, in the county of Woodford andState of Illinois, have invented a new and useful Veterinary DentalFloat, of which the following is a specification.

This invention relates to veterinary dental implements for filing,smoothing, leveling, and reducing the teeth of horses and other animalswhen required, and has for its object to improve the construction andincrease the efficiency of devices of this character.

With these and other objects in view, which will appear as the nature ofthe invention is better understood, the same consists in certain novelfeatures of construction, as hereinafter fully described and claimed.

In the accompanying drawings, forming a part of this specification, andin which corresponding parts are denoted by like designating characters,is illustrated the preferred form of the embodiment of the inventioncapable of carrying the same into practical operation, it beingunderstood that the invention is not necessarily limited thereto, asvarious changes in the shape, proportions, and general assemblage of theparts may be resorted to without departing from the principle of theinvention or sacrificing any of its advantages.

In the drawings thus employed, Figure 1 is a plan view of the improvedimplement. Fig. 2 is a sectional elevation of the head portion of theimplement. Fig. 3 is a plan view of the head portion with theabrading-disk removed. Fig. L is a detached perspective view of one ofthe abrading-disks.

The improved implement comprises an arm or stock 10, having at one end acircular hollow head 11, open at one side, and with an intcrnal circularshoulder 12 to form a bearing for supporting a disk 13, having its outersurface provided with suitable abrading-furrows or the like, the diskthus being rotative upon the shoulder and supported from lateralmovement by the annular rib 14, forming the terminal of one side of thehead portion. Gentrally of the head portion a transverse bearing 15 isformed, and rotatively engaging this hearing is the hub 16 of abevel-gear 17,

the hub of the gear being extended next to the disk 13 for entering asocket therein, as shown in Fig. 2.

The hub 16 of the gear 17 is internally threaded, and the disk 13 issecured thereon by a cap-screw 18, while a binding-plate 19 is securedby a cap-screwQO, passing through the plate and the rear side of thehead portion 11 and into the hub 15 of the gear.

The gear 17 is provided with a cavity 21, in which a stud 22 on the rearside of the disk 13 fits when the parts are united to com plete thecoupling of the parts.

A rod 23 is mounted for rotation in the arm 10 and has formed on one enda pinion 21 for engaging the bevel-gear 17 and connected at the otherend by suitable means to a flexible shaft, (indicated at 25,) by whichmeans the rod is operated. By this simple means it is obvious that thedisk 17 may be rapidly rotated for application to the tooth requiringattention and held in contact there with and adjusted to any desiredextent by the relatively long arm 10, which serves as a lever to assistin operating the device.

The disk 13 is provided with a plurality of tangentially-disposedfurrows 26, forming the cutting or abrading surface, and provided with acircular channel 27 in the abrading-face, the channel being eccentric tothe disk, so that as the disk is rotated the material cut from the toothgathers in this channel and is thus prevented from clogging the disk,while at the same time by reason of the eccentric form of the channelits presence does not cause an irregular action, as will be obvious. Thedisk 13 by this arrangement is readily detachable by simply removing thescrew 18 to enable disks with different abrading-surfaces to besubstituted, and by furnishing a plurality of the disks of differentforms or fineness of dress the scope of the implement may be increasedto any required extent.

It will be noted that the furrows 26 extend above the inclosing rib 14,so that the whole surface of the disk is available for action on thetooth, and no danger exists of the rib interfering with the action.

Having thus described the invention, what is claimed is- 1. A veterinarydental float having an ab loo rading-disk provided with tangentialabrading-furrows and an eccentric channel intersecting the furrows, andmeans for operating said disk.

2. In a veterinary dental implement, a supporting-arm terminating in acircular socket, a disk mounted for rotation in said socket and providedwith tangential abrading-furrows and with a circular channel in saidfurrows disposed eccentrically to said disk, and means operating throughsaid arm for rotating said disk.

3. In aveterinary dentalinstrument, an arm having at one end a headprovided with an internal circular shoulder, a disk having anabrading-surface and mounted for rotation upon said ,shoulder, and meansoperative through said arm for rotating'said disk.

4:. A veterinary dental float having a head provided with a socket, agear mounted in the socket and having its hub extending rearwardlythrough a bearing in the head, means for detachably securing the hub ofthe gear in place, a disk detachably secured to the face of the gear andmounted in said socket, and operating means including a pinion meshingwith said gear.

5. In a veterinary dental instrument, an arm having at one end a headprovided with an internal circular shoulder and with a centraltransverse bearing, a gear having ahub extending through said bearingand likewise extending beyond the opposite face of the gear andinternally threaded, a stop-plate bearing upon the rear face of saidhead and held in position by a cap-screw operating through said plate,and into said hub within said bearing, a disk having anabrading-surface, and mounted for rotation upon said shoulder, andprovided with a socket for engaging the adjacent portion of said hub,and held in position by a cap-screw' operating through said disk, andinto said gear-hub, and with a stud extending into a cavity in saidgear, a rod mounted for rotation in said arm, and terminating in apinion for engaging said gear, and means for rotating said rod.

In testimony that we claim the foregoing as our own we have heretoaflixed our signatures in the presence of two witnesses.
